Musar su Geremia 6:28

The third section: One who goes talebearing. And we were warned about this in the Torah, as it is stated (Leviticus 19:16), “You shall not go talebearing among your people.” And this is also called evil speech. And he is included in the group of slanderers - as our Rabbis, may their memory be blessed, mentioned about Doeg the Edomite that he was involved in evil speech because he told Saul, and said to him that David came to the house of Ahimelech. And there is no counting the damage of talebearing: For it increases hatred in the world and makes people stumble on that which is written in the Torah (Leviticus 19:17), “You shall not hate your brother in your heart.” And behold the world stands upon peace (Avot 1:18) - so due to hatred, the world deteriorates, as we have discussed earlier. And many times, the talebearer puts a sword in the hand of his fellow to kill his companion, as it is written (Ezekiel 22:9), “Talebearing men were in your midst, intent on shedding blood.” And it is [also] stated (Jeremiah 6:28), “They are copper and iron - they are all stubbornly defiant; they go talebearing; all of them act corruptly.” And our Rabbis (Arakhin 15b) called talebearing, “Third speech, because it kills three: The one who speaks it, the one who accepts it; and the one about whom it is said” - as you know from the matter of Doeg, such that he was banished [from the world to come] on account of the talebearing; the priests were killed; and Saul was punished for accepting the talebearing.
